Just a point of clarification, for all of these hosts, 1 of these interfaces is connected to my 1Gbps switch, and the other interface is connected to my 10Gbps switch.
enp4s0f0 is physically connected to 1 switch.
eno1 is physically connected to another.
But those interfaces are also bridged - and controlled - by oVirt itself.
Is it possible that oVirt took them down for some reason.
I'm not sure what to make of this, but looking at /var/log/messages on all 3 of the hosts,it appears that the kernel disabled my oVirt networks at the same exact time on all 3 hosts.
This occurred twice this morning, once around 8am and again around 8:30am:
ovirtmgmt is the storage network.
Private is the frond-end network.
I actually don't have *any* backup storage domains currently, and no backups to speak of, so that wouldn't have been a cause from this morning.
My goal for this week is to install a 4th physical server with some spinning disks, and expose those as an NFS mount point so that I can build a backup domain.
I also hope to get the 10Gbps network cards installed on the remaining two hosts, to get 10Gbps connectivity up and running between all 3 of the HCI hosts.

The symptoms are similar to a loss of quorum (like in a network outage/disruption).
Check the gluster logs for any indication of the root cause.
As you have only one gigabit network, consider enabling cluster choose-local option which will make FUSE client to try to read from local brick instead of a remote one.
Theoretically congestion on storage network could be the root cause, but this is usually a symptom and not the real problem. Maybe you got too many backups running in parallel ?
